Geofenced mission critical push-to-talk (mcptt) talk groups

A system comprising:

• at least one processor;
• and
• at least one non-transitory, computer-readable storage medium storing instructions that, when executed by the at least one processor, cause the system to:
• receive a request to create a Mission Critical Push-to-Talk (MCPTT) talk group usable to communicate between members of the MCPTT talk group,
• wherein the request to create the MCPTT talk group includes an indication of a geofence within which the members of the MCPTT talk group can communicate;
• in response to receiving the request to create the MCPTT talk group, create the MCPTT talk group;
• receive a location estimate of a first mobile device, the location estimate indicating that the first mobile device is within the geofence;
• in response to receiving the location estimate indicating that the first mobile device is within the geofence, transmit, to the first mobile device, an indication that the MCPTT talk group is joinable;
• receive, from the first mobile device, a request for a first user of the first mobile device to join the MCPTT talk group;
• and
• in response to receiving the request for the first user to join the MCPTT talk group, add the first user of the first mobile device to the MCPTT talk group such that the first mobile device can be used to communicate with the members of the MCPTT talk group.
